Description

Technical Field

[0001] This utility model relates to the field of drying tower technology, specifically a dust removal device for a grain drying tower. Background Technology

[0002] With the rapid development of the national economy, people have put forward higher requirements for the taste and quality of grains, especially for cooked rice made from finished rice. They require the rice to have a clean appearance, a fragrant aroma, and a moderate texture. If the grain is dried in the traditional open field or on the road, the quality of the grain cannot be guaranteed. At present, most grains are dried in drying towers, thereby ensuring the quality and taste of the grains.

[0003] According to a public announcement of a grain drying tower with a dust removal mechanism for grain drying (publication number: CN215113683U), the dust removal mechanism in the above application can suck up the dust inside the tower and attach it to the sponge pad, thereby achieving the purpose of dust removal. Moreover, the sealing cover is easy to disassemble and assemble, making it convenient to replace and clean the sponge pad inside the threaded tube. Furthermore, the fastening ring can also easily fix the box to the tower body, thus improving the installation stability of the box.

[0004] However, as the drying tower continues to operate, the sponge pads gradually become saturated, significantly reducing their dust removal efficiency. At this point, to ensure effective dust removal, the sponge pads must be replaced or cleaned promptly. However, in existing designs, replacing or cleaning the sponge pads is cumbersome, requiring the entire dust removal mechanism to be stopped, the sealing cover removed, the sponge pads taken out of the threaded tubes for replacement or cleaning, and then reassembled. This process is not only time-consuming but also causes a temporary interruption of the dust removal function, thus affecting the drying tower's continuous operation and overall dust removal efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a dust removal device for a grain drying tower to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for a grain drying tower, comprising a drying tower, a dust removal box disposed on the surface of the drying tower, a base plate fixed to the surface of the drying tower, the dust removal box fixed to the top of the base plate, and a dust removal assembly for removing dust from the interior of the drying tower and a replaceable assembly for easy replacement disposed on the surface of the dust removal box. The dust removal assembly includes: a partition plate, a stabilizing plate, a filter plate, a fixing plate, an induced draft fan, a duct, a T-joint pipe, and a sealing door. The replaceable assembly includes:

[0007] A fixed cylinder penetrates the dust collector and is fixedly connected to it. A piston rod is connected to the inner side of the fixed cylinder. A connecting plate is fixed to the bottom of the piston rod. A spring is fixed to the top of the piston rod. The top of the spring is fixed to the inner wall of the fixed cylinder.

[0008] Preferably, the replacement assembly further includes an L-shaped rod, which is fixed to the top of the piston rod. The top of the L-shaped rod passes through the fixed cylinder and is slidably connected to the fixed cylinder. The top of the connecting plate is fixed with a connecting cylinder, and the top of the connecting cylinder has a sliding groove. A sliding rod is slidably connected to the inner wall of the sliding groove. A rubber column is fixed to the top of the sliding rod, and a second spring is fixed to the bottom of the sliding rod. The bottom of the second spring is fixed to the bottom of the inner wall of the sliding groove. The replacement assembly also includes a limiting member. Pulling one set of L-shaped rods causes the piston rod to move the connecting plate, connecting cylinder, sliding rod, and rubber column upwards simultaneously. The rubber column disengages from one of the exhaust ports of the three-way pipe. Pulling another set of L-shaped rods causes the other set of piston rods to move the connecting plate, connecting cylinder, sliding rod, and rubber column upwards, thereby blocking the other exhaust port of the three-way pipe with the rubber column.

[0009] Preferably, the limiting component includes a vertical plate fixed to the top of the dust collector box. A fixed block is fixed to the surface of the vertical plate, and a sliding block is slidably connected to the surface of the vertical plate. A magnet is fixed to the surface of the vertical plate and magnetically connected to the sliding block. A movable groove is formed on the surface of the L-shaped rod, and a movable block is slidably connected to the inner wall of the movable groove. A spring is fixed to the surface of the movable block, and the end of the spring away from the movable block is fixed to the inner wall of the movable groove. When the L-shaped rod moves upward, the side of the movable block away from the inclined plane abuts against the top of the fixed block, thus limiting the movable block and the L-shaped rod. When the L-shaped rod is pulled up again, the movable block is above the sliding block, the spring is released, and the movable block abuts against the top of the sliding block. At this time, the spring is released, and the L-shaped rod and the movable block drive the sliding block to move downward. When the sliding block is in contact with the surface of the fixed block, the movable block moves along the surface of the sliding block and the fixed block, thus releasing the limitation on the movable block and allowing the exhaust port of the three-way pipe to work alternately.

[0010] Preferably, the partition is fixed to the inner wall of the dust collector, and stabilizing plates are fixed to the partition, the surface of the dust collector, and the inner wall of the dust collector. A filter plate is placed on top of the stabilizing plate, and a fixing plate is fixed to the top of the dust collector. An induced draft fan is fixed to the surface of the fixing plate. A duct is fixed to the suction end of the induced draft fan, and the end of the duct away from the induced draft fan is connected to the drying tower. A three-way pipe is fixed to the suction end of the induced draft fan, and the end of the three-way pipe away from the induced draft fan is connected to the dust collector. A sealing door is installed on the surface of the dust collector. Two sets of sealing doors and filter plates are provided. When the induced draft fan is turned on, the dust from the grain enters the dust collector through the duct and is filtered by the filter plates, so that the dust remains in the dust collector. When the filter plates need to be replaced, the dust in the dust collector can be cleaned at the same time by opening the sealing door.

[0011] Preferably, the drying tower has a feed inlet at the top and a discharge outlet at the bottom. A motor is fixed to the top of the drying tower, and the output shaft of the motor passes through the drying tower. A stirring rod is fixed to the surface of the output shaft of the motor. An air outlet is provided on the surface of the dust collector. When the motor is turned on, the stirring rod rotates to stir the grain. At the same time, the heating plate is turned on to dry the grain.

[0012] Preferably, the end of the movable block away from the spring is set as an inclined surface, the fixed block is set as a right-angled triangular block, and the sliding block is set as a right-angled trapezoidal block. The inclined surface of the movable block is abutted, which allows the movable block to enter the movable groove without affecting the movement of the L-shaped rod. When the sliding block and the fixed block are in contact, the movable block can move along the surface of the sliding block and the fixed block, which can release the limitation on the movable block.

[0013] Preferably, the replacement components are provided in two sets, and both sets of replacement components are symmetrically arranged with the center line of the dust collector as the axis of symmetry, which facilitates alternating operation and allows the two sets of filter plates to perform filtration work alternately.

[0014] Compared with the prior art, this utility model provides a dust removal device for a grain drying tower, which has the following beneficial effects:

[0015] 1. The dust removal device of this grain drying tower, through the set replacement component, pulls a set of L-shaped rods, and the piston rod drives the connecting plate, connecting cylinder, sliding rod, and rubber column to move upwards simultaneously. The rubber column disengages from one of the exhaust ports of the three-way pipe, pulls another set of L-shaped rods, and the other set of piston rods drives the connecting plate, connecting cylinder, sliding rod, and rubber column to move upwards, so that the rubber column blocks the other exhaust port of the three-way pipe. The corresponding set of sealing doors for the filter plate that needs to be replaced is opened, and the filter plate can be pulled out for replacement without stopping the dust removal work, thus improving work efficiency. The set limit component can limit the L-shaped rods to stabilize the rubber column.

[0016] 2. The dust removal device of the grain drying tower, through the dust removal components, turns on the induced draft fan, and the dust of the grain enters the dust removal box through the duct. It is filtered by the filter plate, so that the dust is retained in the dust removal box. When the filter plate needs to be replaced, the dust in the dust removal box can be cleaned at the same time by opening the sealed door. Attached Figure Description

[0024] like Figures 1-6As shown, this utility model provides a technical solution: a dust removal device for a grain drying tower, including a drying tower 1, a dust removal box 2 disposed on the surface of the drying tower 1, a base plate 3 fixed to the surface of the drying tower 1, the dust removal box 2 fixed to the top of the base plate 3, and a dust removal component 8 for removing dust from the inside of the drying tower 1 and a replaceable component 9 for easy replacement disposed on the surface of the dust removal box 2. The dust removal component 8 includes: a partition plate 80, a stabilizing plate 81, a filter plate 82, a fixing plate 83, an induced draft fan 84, a duct 85, a three-way pipe 86, and a seal. Door 87, replacement component 9 includes: a fixed cylinder 90, which penetrates the dust collector 2 and is fixedly connected to the dust collector 2; a piston rod 92 is piston-connected to the inner side of the fixed cylinder 90; a connecting plate 91 is fixed to the bottom of the piston rod 92; a spring 93 is fixed to the top of the piston rod 92; the top of the spring 93 is fixed to the inner wall of the fixed cylinder 90; replacement component 9 also includes an L-shaped rod 94, which is fixed to the top of the piston rod 92, and the top of the L-shaped rod 94 penetrates the fixed cylinder 90. Furthermore, the L-shaped rod 94 is slidably connected to the fixed cylinder 90, and the top of the connecting plate 91 is fixed with a connecting cylinder 95. The top of the connecting cylinder 95 is provided with a sliding groove 96, and a sliding rod 97 is slidably connected to the inner wall of the sliding groove 96. A rubber column 900 is fixed to the top of the sliding rod 97, and a second spring 98 is fixed to the bottom of the sliding rod 97. The bottom of the second spring 98 is fixed to the bottom of the inner wall of the sliding groove 96. The replacement assembly 9 also includes a limiting member 99. Two sets of replacement assemblies 9 are provided, and both sets of replacement assemblies 9 are symmetrical about the center line of the dust collector 2. With axial symmetry, pulling one set of L-shaped rods 94 causes the piston rod 92 to move the connecting plate 91, connecting cylinder 95, sliding rod 97, and rubber column 900 upwards simultaneously. The rubber column 900 disengages from one of the exhaust ports of the three-way pipe 86, pulling the other set of L-shaped rods 94 causes the piston rod 92 to move the connecting plate 91, connecting cylinder 95, sliding rod 97, and rubber column 900 upwards, thus blocking the other exhaust port of the three-way pipe 86. At this time, the other set of filter plates 82 performs filtration.

[0025] The limiting component 99 includes a vertical plate 990, which is fixed to the top of the dust collector 2. A fixing block 991 is fixed to the surface of the vertical plate 990, and a sliding block 992 is slidably connected to the surface of the vertical plate 990. A magnet 993 is fixed to the surface of the vertical plate 990 and is magnetically connected to the sliding block 992. An active groove 994 is formed on the surface of the L-shaped rod 94. An active block 995 is slidably connected to the inner wall of the active groove 994. A spring 996 is fixed to the surface of the active block 995. The end of the spring 996 away from the active block 995 is fixed to the inner wall of the active groove 994. The end of the active block 995 away from the spring 996 is set as an inclined surface. The fixing block 991 is set as a right angle. The triangular block and the sliding block 992 are set as right-angled trapezoidal blocks. When the L-shaped rod 94 moves upward, the side of the movable block 995 away from the inclined plane abuts against the top of the fixed block 991, which limits the movable block 995 and the L-shaped rod 94. When the L-shaped rod 94 is pulled up again, and the movable block 995 is above the sliding block 992, the spring 3 996 is released, and the movable block 995 abuts against the top of the sliding block 992. At this time, the spring 1 93 is released, and the L-shaped rod 94 and the movable block 995 drive the sliding block 992 to move downward. When the sliding block 992 is in contact with the surface of the fixed block 991, the movable block 995 moves along the surface of the sliding block 992 and the fixed block 991, which releases the limitation on the movable block 995.

[0026] The partition 80 is fixed to the inner wall of the dust collector 2. The partition 80, the surface of the dust collector 2, and the inner wall of the dust collector 2 are all fixed with stabilizing plates 81. A filter plate 82 is placed on the top of the stabilizing plate 81. A fixing plate 83 is fixed on the top of the dust collector 2. An induced draft fan 84 is fixed on the surface of the fixing plate 83. A duct 85 is fixed at the suction end of the induced draft fan 84. The end of the duct 85 away from the induced draft fan 84 is connected to the drying tower 1. A three-way pipe 86 is fixed at the suction end of the induced draft fan 84. The end of the three-way pipe 86 away from the induced draft fan 84 is connected to the dust collector 2. A sealing door 87 is installed on the surface of the dust collector 2. Two sets of sealing doors 87 and filter plates 82 are provided. When the induced draft fan 84 is turned on, the dust of the grain enters the dust collector 2 through the duct 85 and is filtered by the filter plate 82, so that the dust stays in the dust collector 2. At this time, the air is exhausted through the air outlet 11 to remove dust from the drying tower 1.

[0027] The top of the drying tower 1 is provided with a feed inlet 4, and the bottom of the drying tower 1 is provided with a discharge outlet 7. A motor 5 is fixed on the top of the drying tower 1, and the output shaft of the motor 5 passes through the drying tower 1. A stirring rod 10 is fixed on the surface of the output shaft of the motor 5. An air outlet 11 is provided on the surface of the dust removal box 2. When the motor 5 is turned on, the stirring rod 10 rotates to stir the grain. At the same time, the heating plate 6 is turned on to dry the grain.

[0028] When grain needs to be dried, it is fed into the feed inlet 4, the motor 5 is turned on, the stirring rod 10 rotates to stir the grain, and the heating plate 6 is turned on at the same time to start the grain drying process. Simultaneously, the induced draft fan 84 is turned on, and the dust from the grain enters the dust collection box 2 through the duct 85 and is filtered by the filter plate 82, causing the dust to remain inside the dust collection box 2. At this time, air is exhausted through the exhaust port 11. When the filter plate 82 has been used for a long time and its filtration efficiency decreases, it needs to be replaced. Pulling a set of L-shaped rods 94 will cause the piston rod 92 to drive the connecting... Plate 91, connecting cylinder 95, sliding rod 97, and rubber column 900 move upwards synchronously. At this time, sliding rod 97 enters the sliding groove 96, and spring 2 98 is compressed. Simultaneously, as L-shaped rod 94 moves upwards, it drives movable block 995 to move upwards. At this time, the inclined surface of movable block 995 abuts against the surface of sliding block 992, and movable block 995 enters the movable groove 994. Spring 3 996 is compressed. When movable block 995 is above sliding block 992, spring 3 996 is released, and movable block 995 abuts against the top of sliding block 992. At this time, spring 1 93 is released, and L-shaped rod 94 and movable block 900 move upwards. 995 drives the sliding block 992 to move downwards. When the sliding block 992 is in contact with the surface of the fixed block 991, the movable block 995 moves along the surfaces of the sliding block 992 and the fixed block 991, thus releasing the limit on the movable block 995. At this time, the rubber column 900 disengages from one of the exhaust ports of the three-way pipe 86, pulling the other set of L-shaped rods 94 upwards again. When the surface of the movable block 995 contacts the surface of the fixed block 991, the movable block 995 enters the movable groove 994, and the spring 996 is compressed. When the movable block 995 is above the fixed block 991, the spring... When spring 996 is released, the side of movable block 995 away from the inclined plane abuts against the top of fixed block 991, thus limiting movable block 995 and L-shaped rod 94. This causes piston rod 92 to move connecting plate 91, connecting cylinder 95, slide rod 97, and rubber column 900 upwards, allowing rubber column 900 to block the other exhaust port of three-way pipe 86. At this time, another set of filter plates 82 begins filtration. Open the sealing door 87 corresponding to the filter plate 82 that needs to be replaced, and pull out the filter plate 82 for replacement without stopping the dust removal work, thus improving work efficiency.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
